FTS-125-01-L-DV-A Equivalent & Substitute Parts
Part Overview
The FTS-125-01-L-DV-A is a surface mount rectangular connector header manufactured by Samtec Inc., designed for board-to-board or cable applications. This 50-position, 2-row connector operates across -55°C to 125°C and features gold-plated mating contacts with a 0.050" (1.27mm) pitch. The part is currently active in production with full inventory availability. Substitute parts may be required due to supply chain constraints, design revisions, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation
The FTSH-125-01-L-DV-A qualifies as a direct substitute based on the following critical parameters:
Electrical compatibility is maintained through identical pitch (0.050"), contact type (male pin), contact material (phosphor bronze), contact finish (gold), and current rating (3.4A per contact). Both parts operate across the same temperature range (-55°C to 125°C) and meet ROHS3 compliance with MSL 1 rating.
Mechanical compatibility is preserved through matching connector type (header, cuttable), mounting type (surface mount), termination method (solder), fastening type (push-pull), and insulation material (LCP). Both parts feature 50 positions in a 2-row configuration with 0.050" row spacing.
The primary difference between these parts is the insulation height: FTS-125-01-L-DV-A has 0.034" (0.86mm) insulation height, while FTSH-125-01-L-DV-A has 0.099" (2.51mm) insulation height. This dimensional variation may affect board layout and stacking considerations but does not impact electrical performance or core functionality.

Engineering Selection Recommendations
Both FTS-125-01-L-DV-A and FTSH-125-01-L-DV-A are active production parts from Samtec Inc. with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on board layout requirements and available vertical clearance.
The FTS-125-01-L-DV-A with 0.034" (0.86mm) insulation height is suitable for applications with space constraints or compact PCB designs. The FTSH-125-01-L-DV-A with 0.099" (2.51mm) insulation height provides increased structural rigidity and may be preferred for applications requiring enhanced mechanical stability or higher vibration environments.
Both parts maintain full compatibility with identical contact pitch, row spacing, current rating, and temperature operating range. The choice between these variants does not affect electrical performance or signal integrity.
Frequently Asked Questions (FAQ)
Q: Can FTSH-125-01-L-DV-A be used as a direct replacement for FTS-125-01-L-DV-A?
A: Yes, FTSH-125-01-L-DV-A is electrically and mechanically compatible with FTS-125-01-L-DV-A. Both parts share identical pitch (0.050"), contact configuration (50 positions, 2 rows), contact material, and current rating (3.4A per contact). The primary difference is insulation height, which may require PCB layout adjustment.
Q: What is the significance of the insulation height difference?
A: Insulation height affects the vertical profile of the connector on the PCB. FTS-125-01-L-DV-A has 0.034" (0.86mm) height, while FTSH-125-01-L-DV-A has 0.099" (2.51mm) height. This difference impacts available clearance above the connector and may influence component placement in compact designs.
Q: Are both parts RoHS compliant?
A: Yes, both FTS-125-01-L-DV-A and FTSH-125-01-L-DV-A are ROHS3 compliant and suitable for applications requiring environmental compliance.
Q: Do these parts have different moisture sensitivity requirements?
A: No, both parts have identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture handling or baking requirements during storage or assembly.
Q: What is the contact pitch for these connectors?
A: Both parts feature a 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing, maintaining standard spacing for 50-position 2-row header configurations.
